Hello @isun, we will be sure to make up this upvote. The current voting pattern for upex is 1x every 24 hours. We are in the process of changing it to once a day starting midnight china time, but until then upvotes will miss if you post more often than every 24 hours...

Keep that in mind should you experience a missed upvote in the future until we make the timezone change. Thank you for using our service! :)
